Specification of Letters Patent.

Tate'h'ted mama e, "1am.

Application filed November 11, 1907. Serial Nb. 401,652.

To all whom it may concern:

Be it known that I, HARRY F. BUSHONG, a citizen of the United States, residingin the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Im rovements in Temporary Bin ers or Looseheet Holders, of which the following is a specification.

This invention relates to improvements in temporary binders or loose sheet holders.

My present invention is particularly applicable to the style of binder illustrated and described in my application for Letters Patent filed December 31, 1906, Serial No. 350,267, finally allowed July 11, 1907, and is a modification, and, in some respects, an improvement on the structure there illustrated, although it is applicable for use in various relations.

The main objects of this invention are: first, to provide an improved temporary binder or loose sheet holder which may be very quickly and easily adjusted or manipulated to remove or insert the sheets or leaves second, to provide an improved temporary binder or loose sheet holder which is of very large capacity; that. is, it is adapted to hold a very large number of leaves in proportion to its size, and, at the same time, is effective for holding a small number of leaves; and third, to provide an improved temporary binder or loose sheet holder with a back which is automatically adjusted with the ad justing of the binder, and one which may be easily kept centered as the book is adjusted for different quantities of leaves.

Further objects, and objects relating to details of construction, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The inventlon is clearly defined and point ed out in the claims.

A structure embod ing the features ofmy invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which,

Fi ure 1 is a rear view of a structure embodying the features of my invention, the

I covers being open or extended, the rear walls of the covers being removed, and also portions of the back being broken away to better show the mechanism; Fig. 2 is an inside View, the covers being open or extended,

with parts of the inner wall of the covers broken awayto bettershow the mechanism, and leaves or sheets being illustrated in conventionalfor'm'; Fig. 3 is an enlargeddetail, taken on a line corresponding to line 3.3 of Fig. 2 Fig. 4 is an enlarged detail section,, taken one line corresponding to line t-4 of Fig. 1; Fig. 5 is an enlarged detail section, taken on a line corresponding to li1 1e5-5 of Fig. 1; 6 is an enlarged detail section, taken on a line corresponding to line 6 of Fig. 2, the book being shown closed and the binding cords being shown in fulllines.

In the drawing, similar numerals of reference refer to similar parts throughout the several views and the sectional, views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the covers 1 are preferably formed with chambers 'thereinto the adjusting mechanism of the receive binder. The binder walls 2 of the covers are preferably of sheet metal on account of strength, so that the, covers may be made comparatively thin. The leaf clamping bars 2 are pivotally mounted on the inner ends of the covers, the hinge members l'fbeing rigidly secured to the covers, and the clamplng bars being secured thereto by pivots, so that he clampin bars and covers may move in eendent y on the opening and closing of the inder. As the details of this connection form no part of my present invention, I do not illustrate the same in detail herein. The covers are connected by the binding cords or strips 5, which are preferably arranged through the clamping bars, as .is illustrated in Fig. 6. These binding cor'd's are connected to the adjustable members or cross bars 6 and 7. One of the adjustable members, as 6, is mounted upon the screw 8, which is adapted to be, manipulated by means of a suitable kej a key-hole opening 9 being provided in t e end of the cover. The cross bar 6 is referabl a spring bar, the advantage of w 'ch wili be hereinafter pointed out. This adjusting mechanism is the same as that illustrated in Letters Patent, No, 851,276, issued to me on the 23rd day of April, 1907. The other cross bar or adjustable member 7 is slidafbly ,mounted on the rack or ratchet bar 10. The rack bar ispreferably arranged throu h the transverse hole 7 in the cross bar. he cross bar 7 is provided with a pawl 11, adapted to eti- Mil . ably arranged loosely on a suitable seat Iprovided therefor on the rack bar, and is eld in or out of its engaging position by means of the spring 12, which is pivoted at 13, so that it may be swung forward to hold the pawl in itsengaging position, or rearward to hold it out of its engaging position. The spring is provided with a finger piece 13, which may be manipulated through the slot 14 in the inner wall of the cover. The cross bar 7 is also preferably provided with a finger piece 15 adapted to be swung up for convemence in adjusting the cross bar.

This finger piece is adapted to swing down onto the cover chamber when not in use. This rack bar, and the connections for the cross bar thereto, illustrated, is substantially that shown in my application hereinbefore referred to. The bar 10 is adjustably supported at its inner end, being arranged in a bearing 16, while its outer end is connected to a pivoted lever 17. The lever 17 is pivoted at 18, and is preferably arranged transversely of the cover at the outer end thereof. The lever 17 is provided with a slot 19 in which the cam 20 is arranged. The swinging end of the lever isheld upon the cam by means of a suitable sli as 21. The cam 20 is rotatably mounte on the cover, preferably being secured by a ringlike hearing 22, as clearly appears in F 4. The cam is adapted to be manipulatef by means of a key, as 23. By this arrangement, the binder may be quickly adjusted to permit the insertion of the sheets or leaves, or the removal of the same. In adjusting the binder'under ordinary 'circumstances,it is intended that the rack bar shall be released or shifted to relieve the binding cords, and the cross bar 7 disengaged from the rack bar, which allows the covers and the leaf clamping bars carried thereby to be drawn apart freely. When it is desired to retract the clam mg bars, it may be done by dra'wing up iilie member 7 on the rack bar as tightly as it is convenient, and then adjusting the rack bar, which puts stress upon the clampin bars to retain the sheets or leaves for han ling. As the book is designed to receive any number of leaves up to its maximum, the cross bar 6 is preferably a spring bar so that the parts will not be subject to excessive strain when the cam is tightened with only a few leaves therein. The rack or ratchet bar is preferably adjusted b means of the lever and cam mechanism ilustrated, as b this mechanism, great power is secured 1n a small compass and it is quite impossible to overstrain the parts, as the continued movement of the cam would release the tension. Another advantage of this adjusting mechanism is that, when the book is in use,that is,

members can be eased off or tightened very quickly. A further advantage of this arrangement is that even binders of large size and containin a great many sheets can be easily adjusted; that is, but little power is required to satisfactorily adjust the binder. The combination of this rapid adjustment mechanism with the screw ad ustment shown in my patent hereinbefore referred to, is desirable on account of the great expansion which is thereby secured. Also, by rovid ing adjustable members for the inding cords in each cover, the back strip 24 ma be kept properly centered. This is of a vantage, as will be obvious, the title of the book appearing on the back strip. The ends of the back stri are arranged to telescope in the covers and are connected to the cross bars by means of elastic bands 25. This insures the keeping of the back piece taut, and also permits the adjustment of the cross bars. -It is obvious that when thesheets of the book are varied greatly by ad'usting both of the adjustable members 6 an 7, the back strip is kept properly centered.

I The clamping bars 3 are provided with openings 26 through which the binding cords or strips are arranged. The clamping bars are preferabl formed of strips of wood having slots cut In their inner edges and strips of metal 27 arranged at their inner corners.

These strips of metal strengthen the woodand form bearings for the binding cords.

' I have illustrated and described my invention in detail in the form preferred by me and embodied in the structures of my patent and application hereinbefore referred to. 1 am,

however, aware that it is capable of being embodied in other structures, and as such embodiment will be readily understood to those skilled in the art to which this invention relates, I do not illustrate the same herein.
